Myself, I dont see a problem, I also dont smoke the leaf, as far as I am concerned it's fall, leaves yellow die and fall off to be mulch.
I too do not have anything to PH with, I build my soil, the plants grow, I read the leaves and make any needed changes.
I also do dry cycles to the point of wilt which puts the plant in survival mode, she then eats the leaves. The leaves are storage tanks for mobile nutrients and water, sugar factories, once she starts eating them, like a kid with a candy bar, she will finish them. As they yellow, I give them a gentle tug, if they come off they do, if not they stay another day.
